If you do not live in a two-story house, the attic will be a less comfortable but equally secure substitute. Most can be secured by simply raising the retractable staircase or removing the temporary ladder. Zombies lack the cognitive ability to build a ladder of their own. If you stay quiet, they will not even know that an attic exists. Never use a basement as a shelter. Popular horror flicks have shown that, in a crunch, this subterranean chamber can protect the living from the dead. This is a dangerous fallacy. Burning, suffocating, or simply starving to death in basements have claimed hundreds of lives over the years.
